Automatic Transmission problem #5
The vehicle having this issue was a 2004 Toyota Sienna. Vehicle hesitates/fails to move forward in the following mode: after braking, when the vehicle is still moving between 5 to 15 mph, the van does not respond to accelerator pedal input; vehicle hesitates with no movement forward, then shifts hard into first gear and lurches forward. We have had 2 close calls, waiting for the vehicle to respond to accelerator pedal input. Also, accelerator pedal has a dead spot. The first half inch of pedal causes no response from vehicle). This "dead spot" along with the hesitation noted above can result in a 2 second response failure from the vehicle. This situation has put my family in harms way on numerous occasions.

Automatic Transmission problem #7
The car involved was a 2004 Toyota Sienna. While approaching a left hand turn off a 4 lane undivided highway I saw a vehicle approaching in the middle most lane with its left turn signal on which I interpreted as a sign that the vehicle was going to make a left turn where I was also turning. But it turned out the turn signal must have just been forgotten about and the vehicle was intending to continue travelling straight. By this time I had already started my turn and was in the path of the oncoming vehicle. When I realized that the vehicle was not going to turn I floored the accelerator to get out of its way. The Sienna seemed to slow down violently as all passengers in my Sienna lurched forward, and then the transmission finally seemed to kick in after what seemed like a couple of seconds of sitting helplessly in the path of the oncoming vehicle, which had to slam on its brakes to avoid colliding with us. This acceleration hesitation could have been much more dangerous if the other driver had not been driving defensively. The failure date was Tuesday, Jul. 6, 2004.

Automatic Transmission problem #14
The car involved was a 2004 Toyota Sienna. Vehicle transmission appears to have a significant delay, dead spot or trouble deciding what gear it wants to be in. Primarily when accelerating if hesitation or a lifting of the pedal takes place and then gas is applied again the car lurches after hesitation and downshifts jerking the car. This can't possibly be healthy for the vehicle transmission long term as well as other car parts. I have had to change my driving habits to account for the poor design of the transmission. I've registered my complaint w/the dealer and they've checked to see if the latest software was on my vehicle and it was. They also indicated that there have been other complaints of this type. The major concern is long term and if my transmission goes bad 3-5-7-10 years from now, how much of this is actually Toyota's fault from poor design but then I have to incur the cost. At a large price tag initially this is not fair to the consumer. This automatic transmission issue occurred Sun., Jul. 18, 2004.

This automatic transmission problem happened on Wednesday, Dec. 1, 2004.
Automatic Transmission problem #16
I have a 2004 Toyota Sienna with a transmission hesitation problem. (a problem toytoa denies but there are thousands of complaints about it to dealers) it is dangerous in snowy conditions as the 2 second hesitation results in a slowing down before an abrupt upshift/power surge that breaks the wheels loose in the snow. This then causes the traction control system to engage. I was stuck repeatedly and in many dangerous conditions in the mountains in an attempt to get to a ski area due to this problem. Toyota needs to have some pressure put on them. This problem occurred on Mar. 4, 2005.

The VIN of the problem Sienna is 5TDBA22CX4_. 2004 Toyota Sienna xle van. When accelerating from a coast the van hesitates. Have to press the accelerator harder to force a hard downshift. This is very dangerous when a predictable acceleration is needed. It seems like the transmission control gets confused on when to downshift.

The vehicle was a 2004 Toyota Sienna. Vehicle hesitates and lurches forward on acceleration. Driver gets jerked forward at an abnormal rate. After acceleration upon leaving a stoped state vehicle does not respond and/or hesitates for a second then lurches forward. Dealer has been notified many times and they tell me this is a characteristic with the new fly wheel design in the Toyotas. They agree it is not right but tell me there is nothing I can do about it?? as a consumer this in unacceptable. Am starting to have neck problems as a result of doing a lot of local in town driving and constantly stopping and starting with being jerked around in my van. Even the passengers feel it. I think this is a major safety issues since it can create physical damage to the driver and cause an accident if van does not respond to accelerator when expected too.
